RTS OPTIONS + IGNORED AT&R1 CTS TRACKS AT&R0 RTS The modem assumes that RTS is always ON and ignores the serial port signals. (Default) Delay before CTS responds to RTS's change. The delay is set in S26. Note: Effective only in synchronous mode. This setting is ignored in asynchronous mode. RTS is always used as a hardware flow control signal in this case. DSR OPTIONS + ALWAYS ON DATA SET READY AT&S0 AT&S1 The modem forces DSR to always remain ON. (Default) According to ITU-T. DSR ON during handshake. If S41.5=1, DSR follows CD, and pulses off for 0.5 sec for CD on-off transition. If S44.4=1, DSR follows DTR. COMMAND ECHO + ENABLED DISABLED ATE1 ATE0 The modem echoes commands. (Default) The modem does not echo commands. RESULT CODE + ENABLED DISABLED ATQ0 ATQ1 ATQ2 The modem returns result codes. (Default) The modem does not return result codes. If S40.1=1, the modem does not return result codes in answer mode. DTE ASYNC SPEED 230400 115200 76800 57600 38400 19200 16800 14400 Selects DTE port asynchronous serial speed.
